본 고안은 초기에 전기장판 표면온도를 빠른 시간내에 도달시켜 주는 전기 장판 금속 온도 제어 회로에 관한 것이다.The present invention relates to an electric sheet metal temperature control circuit that initially reaches the electric sheet surface temperature in a short time.

종래의 전기 장판의 경우는 초기에 전원을 인가하였을때 전기장판 표면온도가 정상온도 까지 도달하는 데 장시간이 소요되어서 사용자에게 불편함을 주었다.In the case of the conventional electric blanket, when the power is initially applied, it takes a long time for the electric blanket surface temperature to reach the normal temperature, which is inconvenient for the user.

따라서, 본 고안의 목적은 전술한 결점을 해결하기 위해 안출한 것으로, 통상적으로 전기 장판에 사용하는 역저지 3극 SCR 소자 케이트에 N케이트 SCR형 PUT (Programmable Unijunction Transistor)소자를 이용한 방전형 타이머 회로를 구성시켜 전기장판의 발열량을 증대함으로써 장판표면온도를 짧은 시간애에 원하고자 하는 온도를 상승시키는 금속온도제어회로를 제공하는데 있다.Accordingly, an object of the present invention is to solve the above-described drawbacks, and is a discharge timer circuit using an N-kate SCR type PUT (Programmable Unijunction Transistor) element in a reverse-stop three-pole SCR element gate that is typically used for electric blankets. It is to provide a metal temperature control circuit for increasing the temperature of the sheet surface temperature in a short time by increasing the calorific value of the electrical plate by constructing a.

이하 첨부된 도면에 의거하여 본 고안을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제1도에서 급속제어회로(10)와 표시점등 회로(20)는 본 고안의 요부이고, 나머지 부분(30)은 공지된 일반 전기장판 온도제어회로이다.In FIG. 1, the rapid control circuit 10 and the indicator lighting circuit 20 are main parts of the present invention, and the remaining part 30 is a known general electric field temperature control circuit.

도면에서 알수 있는 바와 같이 공지된 일반 전기 장판 온도제어회로(30)는 교류전원이 온도 조절용 저항기(VR)와 직렬 연결된 감지선(Hz)과 트리거 소자인 2극 쌍방향 다이리스터(S7)을 거쳐서 SCR(S6)의 게이트 단자에 연결되고, 또 다른 교류전원선은 전류억제 다이오드(D3)와 병렬로 연결된 전기 장판 표면을 발열시켜주는 발열선(H1)에 전원 라인 노이즈 억제용 쵸오크 코일(CH)을 거쳐 SCR(S6)의 캐소드에 연결되어 있다.As can be seen in the drawing, the known general electric plate temperature control circuit 30 has an AC power supply via a sensing line (Hz) connected in series with a temperature regulating resistor (VR) and a two-pole bidirectional thyristor (S 7 ) that is a trigger element. Another AC power line connected to the gate terminal of the SCR (S 6 ), and a choke coil for suppressing the power line noise on the heating line (H 1 ) that heats the surface of the electric sheet connected in parallel with the current suppression diode (D 3 ) It is connected to the cathode of SCR (S 6 ) via CH).

이와 같은 종래의 회로에 본 고안인 금속온도 제어회로(10)와 표시점등회로(200를 연결하는데, 교류전원 전압이 반파 정류 다이오드(D4)를 거쳐 저항(K14)과 정전압 다이오드(D5)에 인기되도록 연겨하여서 직류전압(Vcc)이 공급되는 한편, 충전용 콘덴서(C3)와 금속 온도 스위치(SW2)는 저항(R7)을 거쳐서 트랜시즈터(Q1)의 베이스에 연결하고, 스위치(SW2)와 또 다른 단자는 트랜지스터(Q1) 콜렉터에 연력하는 한편 직류전압(Vcc)에도 연결되도록 하며, 트랜지스터(Q1)의 에미터는 저항(R8)을 거쳐 PUT(S1) 에노우드에 연결된다.In this conventional circuit, the metal temperature control circuit 10 and the display lighting circuit 200 of the present invention are connected to each other, and the AC power voltage passes through the half-wave rectifying diode D 4 and the resistor K 14 and the constant voltage diode D 5. DC voltage (Vcc) is supplied to connect to popular), while charging capacitor (C 3 ) and metal temperature switch (SW 2 ) are connected to base of transceiver (Q 1 ) via resistor (R 7 ). In addition, the switch SW 2 and the other terminal are connected to the collector of the transistor Q 1 while being connected to the DC voltage Vcc, and the emitter of the transistor Q 1 is connected to the resistor R 8 through the PUT (S). 1 ) It is connected to the enoud.

그리고, 저항(R5) (R10)으로 분압된 DC공급 전압을 상기 PUT(S1)의 게이트 신호로 하여 나타나는 출력신호를 트랜지스터(Q2)의 베이스에 연결되고, 트랜지스터(Q2)의 에미터에는 저항(R9)을 통하여 스우칭 다이오드(S3) (S2)를 거쳐 위상제어용 SCR(S6)의 게이트에 연결하는 한편, 스위칭 다이오드(S5)를 거쳐 저항(R11)을 통해 표시점등 SCR(S4)의 게이트에 연결함과 동시에 저항(R12)을 거쳐 SCR(S4)캐소드에 연결하여 저항(R13)을 통해 표시 램프(LED)에 접속된다.Then, the resistance (R 5) and (R 10) connected to the output signal appearing in the DC supply voltage divided by the gate signal from the PUT (S 1) to the base of the transistor (Q 2), the transistor (Q 2) emitter has's wooching diode (S 3) via the other hand, the switching diode (S 5) through a (S 2) for connecting the gate of the phase control SCR (S 6) a resistance (R 11) via the resistor (R 9) It is connected to the gate of the indicator light SCR (S 4 ) through and to the SCR (S 4 ) cathode via a resistor (R 12 ) and is connected to the display lamp (LED) through the resistor (R 13 ).

또한, 콘덴서(C3)에 직렬로 급속온도 취소 스위치(SW3)를 연결하여서 구성한 것이다.In addition, the rapid temperature canceling switch SW 3 is connected to the condenser C 3 in series.

이와 같이 구성된 본 고안의 동작 상태를 회로상의 각점 파형도(제2)에 따라 설명하면 급속온도 온스위치(SW2) 양단에 정전압 다이오드(D5)에서 공급되는 DC전압이 걸려 있는 상태에서 금속온도 온스위치(SW2)를 한번 눌러 ON시키면, 콘덴서(C3)에 충전이 됨과 동시에 콘덴서(C3)에 충전된 전위는 트랜지스터(Q1)의 베이스에 전류가 흘러 트랜지스터(Q1)가 도통되면서 PUT(S1)의 에노우드에 전압이 가해 주게 된다.When the operation state of the present invention configured as described above is explained according to the waveform diagram (second) on the circuit, the metal temperature in the state where the DC voltage supplied from the constant voltage diode D 5 is applied across the rapid temperature on-switch SW 2 . If the power is turned oN by pressing the on switch (SW 2) once, the capacitor (C 3) charged as soon at the same time capacitor (C 3) charged potential is the current in the base flowing transistor (Q 1) of the transistor (Q 1) conductive in the As a result, a voltage is applied to the anode of the PUT (S 1 ).

이때, 저항(R5) R6)에 의해서 분할된 비의 전압이 PUT(S1) 게이트에 가해진 전압 보다 PUT(S1)에 노우드 전압이 높게 유지되므로 PUT(S1)는 도통한다.At this time, since the voltage of the ratio divided by the resistors (R 5 ) R 6 ) is maintained higher than the voltage applied to the PUT (S 1 ) gate, the PUT (S 1 ) maintains the PUT (S 1 ).

PUT(S1)가 도통되면 트랜지스터(Q2)로 도통되면서 C점의 파형(제2(c)도)과 같은 펄스가 발생되고, 그리고, 이 신호는 스위칭 다이오드(S2) (S3)를 거쳐 SCR(S6)의 게이트에 b점의 파형(제2(b)도)과 같은 같은 펄스가 흘러서 SCR(S6)과 직렬 연결된 발열선(H1)에는 거의 반파에 가까운 많은 전류가 흐르기 때문에 장판 표면온도는 빠른 시간 내에 급상승하게 된다.When the PUT (S 1 ) is conducted, it is conducted to the transistor Q 2 and generates a pulse such as the waveform of point C (second (c)), and this signal is a switching diode (S 2 ) (S 3 ). a through SCR (S 6), the waveform of the point b to the gates of (a 2 (b) Fig.) flows through the pulse, such as SCR (S 6) in series with heating wire (H 1) has to flow a large current close to the substantially half-wave Because of this, the surface temperature of the plate is rapidly rising.

이때, 급속온도 온 스위치(SW2)를 누름과 동시에 표시 점등회로(20)의 스위칭 다이오드(S5)에 전류가 흘러 SCR(S4)의 게이트에 트리거가 되어서 SCR(S4)은 "온"상태가 되고, 이에 따라 발광다이오드 (LED)에 전류가 흘러 점등되어서 급속 온도 제어 중임을 표시하게 된다.At this time, the switching diode (S 5) of the light indicative of the temperature on switch (SW 2) rapidly is pressed circuit 20, current flows be a trigger to the gate of the SCR (S 4), SCR (S 4) is "on- State, and a current flows through the light emitting diode (LED), indicating that it is under rapid temperature control.

그리고 콘덴서(C3)에 충전이 된 전압은 서서히 방전 하면서 정해진 시정수에 의해 콘텐서(C3)의 전위는 "0"으로 떨어지게 되어 트랜지스터(Q1)가 "오프"됨과 동시에 PUT(S1)에 에노우드에 전압이 걸리지 않으므로 PUT(S1)가 차단되고 트랜지스터(Q2)도 "오프"되어서 c접의 파형은 "0"으로 나탄난다.And a capacitor (C 3) to the potential of the cone tensor (C 3) by a certain number of time constant and the voltage is charged is slowly discharged is soon as the fall to "0", the transistor (Q 1) "off" at the same time PUT (S 1 Since no voltage is applied to the anode, PUT (S 1 ) is cut off and transistor (Q 2 ) is also “off” so that the waveform of c contact appears as “0”.

이때, 표시점등부(20)도 "오프"되어서 금속 온도 제어가 완료된 것을 자동으로 표시하게 된다.At this time, the indicator lamp 20 is also " off " to automatically display that the metal temperature control is completed.

급속온도 상승 도중 사용자의 임의로 취소 스위치(SW3)를 한번 눌러 주게 되면 콘덴서(C3)에 충전된 전압이 방전 되어 역시 PUT(S1)가 차단된다.If the user presses the cancellation switch SW 3 once during the rapid temperature rise, the voltage charged in the capacitor C 3 is discharged and the PUT (S 1 ) is also cut off.

따라서, 종래의 회로(A)의 감지선(H2)과 발열선(H1) 사이에 임피던스 값의 변화에 의해 다이오드(D2)와 다이악(S7)을 통해서 SCR(S6)의 게이트에는 a전 파형 (제2(a)도)과 같은 파형이 트리거 시켜 주므로 발열선(H1)에 인가되는 전류는 SCR(S6)에 의해 위상제어가 되고, 발열선의 발열량은 본 고안의 급속온도 제어작동시 보다 적게 흐르게 되어 장판 자체 온도를 직접 감지하며, 장판 온도를 자동적으로 일정한 온도를 유지하여서 동작은 온도의 범위는 가변 저항기(VR)의 저항값에 의해 조정이 된다.Therefore, the gate of the SCR (S 6 ) through the diode (D 2 ) and the diaak (S 7 ) by the change of the impedance value between the sensing line (H 2 ) and the heating line (H 1 ) of the conventional circuit (A). Since the same waveform as the previous waveform (Fig. 2 (a)) is triggered, the current applied to the heating line H 1 is phase controlled by the SCR (S 6 ), and the heating value of the heating line is the rapid temperature of the present invention. It flows less during the control operation and directly detects the floor plate itself temperature, and automatically maintains the floor plate temperature so that the temperature range is controlled by the resistance value of the variable resistor (VR).

이상과 같이 장판 표면온도를 짧은 시간내에 원하고자 하는 온도를 도달시켜 주어서 사용자에게 편리함을 줄수 있다.As described above, it is possible to give the user convenience by reaching the desired surface temperature within a short time.
